As the 2014 Country Thunder Festival enters its final day, fans have a few lingering questions:

Will Jason Aldean hop on stage with Colt Ford to sing "Drivin' Around Song"? 

Will Ford hop on Aldean's stage to provide the rap for Aldean's "Dirt Road Anthem" (which Ford co-wrote with country rocker Brantley Gilbert)?

Will Joe Diffie be on stage with Aldean when the headliner sings his homage "1994"?

And, finally, when the dust from the main stage has settled, will Aldean pop up with Tucson's own DJ Du (Duhamel Cassell) in the after-concert Electric Thunder tent like he did at the 2012 festival in Wisconsin?

Ah, so many questions and absolutely no answers. We're all in for some surprises and, sadly, some disappointments. Stay tuned.
